Bioadvantaged nylon: polycondensation of 3-hexenedioic acid with hexamethylenediamine

Various embodiments disclosed relate to electrocatalytic hydrogenation of muconic acid and polymers formed from the reaction products thereof. In various embodiments, the present invention provides an electrocatalytic method to prepare 3-hexene-1,6-dioic acid, 2-hexene-1,6-dioic acid, adipic acid, or a combination thereof, from muconic acid. The method includes passing current through a catalytic cathode in a reactor including an aqueous acidic solution including muconic acid, a supporting electrolyte, and an anode, so as to generate atomic hydrogen on the cathode surface in an amount effective to hydrogenate the muconic acid to yield a product including 3-hexene-1,6-dioic acid, 2-hexene-1,6-dioic acid, adipic acid, or a mixture thereof. Also disclosed is the polymerization of 3-hexene-1,6-dioic acid, 2-hexene-1,6-dioic acid, or a combination thereof with another compound, such as a diamine or a dialcohol, to form a polymer, such as a polyamide or a polyester.

Electrocatalytic hydrogenation of muconic acid

Various embodiments disclosed relate to electrochemical isomerization of muconic acid. In various embodiments, the present invention provides a method to prepare trans,trans-muconic acid. The method can include passing current through a catalytic cathode in a reactor including an aqueous acidic solution including cis,trans-muconic acid, a supporting electrolyte, and an anode, so as to isomerize the cis,trans-muconic acid to yield a product including trans trans-muconic acid.
